根系损伤强度对不同大小毛白杨生长及光合特性的影响
Effects of root damage intensity on the growth and photosynthetic characteristics of hairy poplars of different sizes
[目的]探究不同形态大小与断根起苗移栽强度对毛白杨生长情况和生物量分配及光合特性的影响,为形态差异毛白杨响应根系损伤及应对措施提供理论依据和指导。[方法]采用双因素试验设计,季末在20加仑桶种植的一年生"北林雄株一号"毛白杨中筛选大苗(高317.44cm、胸径14.3mm、地径29.95mm)和小苗(高 154.18cm、胸径 4.43mm、地径 12.44mm))2 种形态苗木,次年 3 月初以低强度损伤(T1-10倍地径)、高强度损伤(T2-…查看全部>>
[Objective]To investigate the effects of different morphological sizes and root-breaking transplanting intensities on the growth,biomass allocation and photosynthetic characteristics of poplar,and to provide theoretical basis and guidance for the response of morphologically different poplars to root damage and countermeasures.[Methods]A two-factor experimental design was adopted,and two types of seedlings(height 317.44cm,diameter at breast height 14.3mm,diam…查看全部>>
